Blackberry, ‘Boysen’ (‘Nectar’)

Boysenberry
Rosaceae
Edible fruit

Trailing, thorny canes can grow 10 ft. in a season, but are commonly controlled by pruning and trellising. Roots are perennial, but canes are biennial: they grow to full length the first season. The second season they bear clusters of white flowers. Extra-large, soft, sweet-tart, reddish berries (botanically an aggregation of drupelets) are covered with a dusty bloom, ripen at midseason.

‘Thornless Boysen’—Thornless, very early (May/June harvest), almost seedless.
